Definitions
- the invention is directed to a method of preparing a current collector surface enriched with cathode active material.
- lithium-ion battery containing lithium cobalt oxide as the layered transition metal oxide cathode
- SONYTM the use hereof receives most attention and is slowly replacing nickel-based and lead acid batteries.

- lithium is a lightweight metal, providing the largest specific energy per weight, and has the greatest electrochemical potential.
- lithium-ion batteries While conventional lithium-ion batteries are not primarily developed for their small dimensions, thin film lithium-ion batteries are composed of materials which are nanometers to micrometers thick. These type of batteries generally consist of a substrate, cathode, anode, electrolyte, current collector(s), and a protection layer. As with anode materials, cathode materials are typically brought onto a predefined surface according to several possible methods. Some examples include the following.

(Thin Solid Films 2013, 528, 217-223 ) report the use of non-reactive radio frequency magnetron sputtering from ceramic targets, performed in a pure argon discharge, to have synthesized multi-structured lithium manganese oxide cathode active materials. In addition, to acquire desired microstructure and electrochemical behavior, a post deposition heat treatment is necessary.
- 3D thin film lithium-ion battery technology consists of planar thin film structures (2D).
